Countries have been taking steps to reduce pollution of all sorts from vessels
at sea for quite a few years now:
Marpol 73/78; is The International Convention for the Prevention of Pollution
From Ships, 1973 as modified by the Protocol of 1978
"MARPOL 73/78 is one of the most important international marine
environmental conventions. It was designed to minimize pollution of the seas,
including dumping, oil and exhaust pollution. Its stated object is: to preserve
the marine environment through the complete elimination of pollution by oil
and other harmful substances and the minimization of accidental discharge of
such substances.
"The original MARPOL Convention was signed on 17 February 1973, but did
not come into force. The current Convention is a combination of 1973
Convention and the 1978 Protocol. It entered into force on 2 October 1983. As
of 31 December 2005, 136 countries, representing 98% of the world's
shipping tonnage, are parties to the Convention.
"All ships flagged under countries that are signatories to MARPOL are subject
to its requirements, regardless of where they sail, and member nations are
responsible for vessels registered under their respective nationalities."
MARPOL contains 6 annexes, concerned with preventing different forms of
marine pollution from ships:
Annex I - Oil
Annex II - Noxious Liquid Substances carried in Bulk
Annex III - Harmful Substances carried in Packaged Form
Annex IV - Sewage
Annex V - Garbage
Annex VI - Air Pollution
There are 161 countries party to the agreement as of 2005.
